homozygous first filial organism,which can undergo mutation or which may be cross-linked or made to breed with other.
Genotype.
Genetic make up of an organism is called its genotype
There is not really enough information in the question to answer it properly. You would need to know what trait the D and d stood for to give a proper answer.If the dog's genotype is Dd and it has the disease, this suggests that the disease is caused by a dominant allele. A healthy bitch would have the genotype dd and half of her pups would have the disease. There is no mate which would produce all heathly pups.If the dog is symptom free then the disease is caused by a recessive allele. In which case the dog should be matted with a dog with the genotype DD to have 100% symptom free pups. Mating Dd to Dd would give 75% symptom free pups and 25% sufferers. Mating the Dd dog to a dd dog would give 50% disease free pups and 50% sufferers.
Assuming the dystonia is hereditary and is a recessive gene which will be called "d" for simplicity, that means the man must be "dd" and the woman is "Dd". This is the only way they could have a child who is "dd" like the father, but not the mother.
The particular set of genes present in an individual is referred to as their genotype. Genes are specific segments of DNA that provide the instructions for various traits and characteristics in an organism. Each individual inherits their genotype from their parents through the process of genetic transmission.
Dd is the heterozygous genotype for dimples.
Phenotype is the observed trait. The dominant trait in this case is observed- D
Genotype.
genotype or phenotype
The genotype of an individual with two different alleles for a specific gene is called heterozygous.

In this case, the mother does not have dimples (Dd) but the father does not have dimples (dd). The Punnett square would show that half of the offspring would have dimples (Dd) and the other half would not have dimples (dd).
There are many types of dwarfism. If D is the autosomal dominant gene for acondroplasia a Dd heterozyote will be an acondroplastic dwarf. The homozygous DD individual dies shortly after birth due to considerable skeletal anomalies.
Cross each allele separately to get the final genotype: AA x Aa = AA, aa, Aa, Aa .: 1/2 Bb x BB = BB, BB, Bb, Bb .: 1/2 cc x CC = Cc .: 1 Dd x dd = DD, dd, Dd, Dd .: 1/2 Ee x Ee = EE, Ee, Ee, ee .: 1/4 FF x ff = Ff, Ff, Ff, Ff .: 1 Multiply all probable fractions: 1/2 x 1/2 x 1 x 1/2 x 1/4 x 1 = 1/64 chance of that specific genotype.
Dd
This procedure is called a test cross. By crossing an individual of unknown genotype with a homozygous recessive individual and analyzing the offspring, geneticists can determine whether the unknown individual is homozygous dominant or heterozygous for a particular trait.
